Abstract
A biosorbent composition, process of preparing and use thereof wherein the biosorbent composition comprises a chitosan-coated substrate. Useful substrates include support materials such as a ceramic support material. The biosorbent composition of the instant invention is useful in treating aqueous systems, including wastewater and aqueous waste streams, by removing undesired heavy metals.
Claims21
A process for preparing a supported chitosan biosorbent useful for the treatment of wastewater which comprises preparing a ceramic support material, preparing a chitosan gel, and coating said chitosan gel to said ceramic support material.
A biosorbent composition comprising a support material coated with chitosan useful for the treatment of wastewater.
A process for treating aqueous systems containing heavy metals comprising adding a chitosan-coated biosorbent to an aqueous system.
A biosorbent composition comprising a support material coated with chitosan, its equivalents and the like useful for the treatment for wastewater.
A process for preparing a biosorbent useful for the treatment of wastewater which comprises preparing a ceramic support material, preparing a gel, and coating said gel to said ceramic support material, wherein said gel comprises chitosan, its equivalents and the like.
A process for treating aqueous systems containing heavy metals comprising adding a biosorbent to an aqueous system, wherein said biosorbent comprises a coating of chitosan, its equivalents and the like.
